Applicationfllcd March 5, 1927. Serial No. 172,585.

My invention relates to shackles and refers particularly to shackles having'rubber, or other resilient material, as a part thereof.

In vehicles, and especially in automobiles,

it is desirable that means be em loyed to absorb, or materially reduce the vi rations incident tov road inequalities and numerous devices have been suggested and adopted for this purpose, the greater portion of which are intended to control the spring movementof the vehicle.

It has been further suggested that resilient shackle means be employed in the connection between the springs and the body of the chassis and it is to this class of shock absorbing shackles that my invention belongs.

In order that a shackle of this character be properly operative it must be strong, im-

possible of separation .due to sudden or strong separating forces, resilient to longitudinal thrusts, while side movement, or twists, are reduced to a minimum.

The device of my invention accomplishes all of the described, and other valuable pur-- poses and comprises a pair of anchoring leaves, of a broken, or open, irregular link, or spiral form, so overlapped asto be intercurved and impossible of separation from so each other by a longitudinal stress, or pull. These anchor leaves are spaced from each other, the spaces being filled with rubber, vor other resilient material, each "leaf carrying an extended member capable of attachment to the vehicle chassis or the vehicle spring.

It is evident, therefore, that any longitudinal expansion or compression of the leaves with respect to each other will be met by resilient resistance, and that any great side movement of .the leaves is im ossible.

In the accompanying drawings ilustrating one form of the device of my invention similar parts are designated by similar numerals.

Figure 1 is a longitudinal cross-section taken through the line 11 of Figure 2.

- Figure 2 is a longitudinal cross-section taken through thevline 2-2 of Figure 1. 50. Figure 3 1s a perspective view of one of the anchor leaves shown in the other figures. The particular form of the device-of my inventionshown in the accompanying drawment of flat material 10.

these are given simply for the purposes of ings comprises a pair of anchor leaves.

Each anchor leaf has anopen curved ele- These anchor leaves are so constructed that when incorpo rated in my device, the free end portions 11, 11 will overlap each other.

F ixedly attached to, or integral with, each anchor, is an abutment 12 extended into the stud 13, which in turn is extended into, or carries, the threaded bolt 14.

In my device, the two anchors are placed in spaced reversed position with respectto. each other, as shown in Figures 1 and 2, and the spaces thus formed are occupied b rubber 19, preferably cemented, or fixed y attached, to the anchor leaves.

In the employment ofmy ,shackle, stud 13 is passed through a corresponding opening in a spring 15 and'retained therein by means of the nut 16 threaded ,uponthe member 14;. The other, stud 13, is passed through a corresponding opening in a chassis element 17 and retained therein by means of the nut 18 threaded upon the member 14.

The body of my shackle, therefore, 06mprises two inter-curved anchor leaves spaced from each other and within a resilient mass, as rubber, having extended portions capable of attachment to a fixed portion of chassis and to a spring. In the operation of my device, a longitudinal thrust will be compensated by the rubber cushion between the two-anchors, thus ab--- sor'bing any sudden longitudinal shock, while a side thrust is likewise absorbed by the rubber cushion.

I do not limit myself to the particulan size, shape, number, arrangement or material of parts as shown and described, as

clearly explaining-the device of my invention. a

WhatIclaim is:

1. In a resilient shackle, in combination,- two over-lapping anchor leaves spacedfrom each other, each anchor having an extended fastening means and a-resilient material be- I tween the anchor leaves.

2. In a resilient shackle, in combination, a resilient mass, two spaced interlocked anchor leaves within the resilient mass and a fastening member carried by each anchor leaf extending outwardly of the resilient i I I I i I I I 3. In a reslhent shackle, 1n combinatlon,

a rubber mass, two spaced curved interlocked anchor leaves Within the rubber mass, a fastenin member carried by each anchor leaf exten ing outwardly of the rubber mass and means carried by the fastening means allowing their attachment to a chassis and a leaf spring.

4. In a resilient shackle, in combination, a rubber mass, two spaced curved interlocked anchor leaves within the rubber mass and fixedly attached to the rubber mass, a fastening member carried by each anchor leaf extending outwardly of the rubber mass and means carried by the fastening means allowing their attachment to a chassis and a leaf spring.

5. In a resilient shackle, in combination, a rubber mass, two spaced curved interlocking anchor leaves within the rubber mass, an abutment carried by each leaf within the rubber mass, and a fastening means carried by each abutment extending outwardly of the rubber mass.

6. In a resilient shackle, in combination,

a rubber mass, two spaced curved interlocked anchor leaves within the rubber mass and fixedly attached to the rubber mass, 'an abutment carried by each leaf within the rubber mass and fixedly attached to the rubber mass and a fastenlng means carried byeach abutment extending outwardly of the rubber mass. Y

7. In a resilient shackle, in combination, a rubbermass, two spaced spiral-like interlocked anchor leaves within the rubber mass, a fastening means carried by each anchor leaf extending outwardly of the rubber mass and means carried by the fastening means allowing their attachment to a chassis and a leaf spring.

8. In resilient shackle, in combination, a

rubber mass, two curved spaced anchor leaves within the mass, so positioned with respect to each other to prevent their longi tudinal separation and a fastening means carried by each leaf extending outwardly of the mass.

'9. In a resilient shackle, in combination, a resilient mass, two-spaced interlocked anchor leaves of flat material within the resilient mass and a fastening member carried by each anchor -leaf extending outwardly of the resilient mass.-

10. In a resilient shackle, in combination, a rubber mass, two spaced curved interlocked anchor leaves of flat material within the rubber mass, an abutment carried by each leaf within the rubber mass and a fastening means carried by each abutment extending outwardly of the rubber mass.

11. In a resilient shackle, in combination, a rubber mass, two spaced spiral interlocked anchor leaves of flat material within the rubber mass, a fastening means carried by each anchor leaf extending outwardly" of the rubber mass and means carried by the fastening means allowing their attachment ber adapted to be secured to another part,

and vibration-dampening material joining and embedding said members,- the' latter being arranged to interlock in s acefd relation, said material forming an insulation between the interlocking portions. I

14. A. combined insulating and vibrationdampening device for connecting relatively movable parts, comprising a member adapted to be secured to one of said parts, a mem-' ber adapted to be secured to another part,

said members including interlocking portions embedded in vibration-dampening insulating material and being movable in all directions while maintaining the interlock.

15. A combined insulating and vibrationdampening device forconnecting relatively movable parts, comprising a member adapted to be secured to one of said parts, a member adapted to be secured to another part, said members including substantially C- shaped portions adapted to interlock in spaced relation, and vibration-dampening insulating material arranged to fill the spaces 'betweenthe interlocking portions and join said members together.

S'gned at Garwood, in the countyof Union and State of New Jersey, this 2nd day of March, 1927.
